Good Rebuttals to Capitalist Arguments?

[Outinleftfield]

What are some good rebuttals to capitalist arguments? For example, Locke's arguments about property and Zakaria's arguments about capitalism being a necessary prerequisite to froming a "middle class" so people can have a "liberal democracy".

Thanks!

Well I always like the slavery one. Here is how it goes. First you ask would they take better care of thing if they owned it. When they answer yes, you fire back with the following. So form your point of view a slave owner would take better care of their slaves, because they own the labor of that slave, instead of rent them(wages).
